Immediate nonocclusal crown placement aids peri-implant tissue maturation for the desired outcome. This retrospective series introduces guidelines for treating sockets based on alveolar septum types. The approach involves immediate dentoalveolar restoration (IDR) and osseodensification (OD) with an autogenous graft for bone preservation. A new protocol for the treatment of the molar interradicular septum during immediate implant placement and/or alveolar ridge preservation/ reconstruction was applied in 12 cases. Preoperative and postoperative CBCT examinations were performed. Socket width was measured and compared between timepoints. At the follow-up (mean: 23.58 ± 9.70 months), the mean preoperative and postoperative socket widths were 9.51 ± 0.40 mm and 11.16 ± 0.30 mm, respectively (17.35% increase; P < .05). IDR with OD is a predictable approach to treat molar sockets during implant placement.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"467-479"},"PeriodicalIF":0.0,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141768339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 31 interventions (29 patients) were grouped into two similar cohorts. Measurements were made on the superimposed STL files before and at least 6 months after treatment, and PROMs were obtained from a questionnaire in two follow-up checks. Data were analyzed using descriptive and inferential statistics. Adverse events and complications were also recorded. Volume reduction was 3 to 4 times less in the ATT group than in the ITT group (P < .05). Patients in the ATT group reported higher levels of perceived inflammation than the IIT group (P = .015), though patients rated satisfaction similarly between the two treatments (9+ on a scale of 1 to 10).

This study compares the Er,Cr:YSGG laser to the traditional scalpel technique for reducing gingival hyperpigmentation, assessing their effectiveness and other relevant factors. For this double-blind randomized trial with a splitmouth design, 40 participants were selected from a university dental clinic and randomly assigned to receive treatment via an Er,Cr:YSGG laser (2,780 nm) or surgical scalpel. Treatment duration was evaluated, and pain intensity and smile satisfaction were assessed postsurgery. The Dummett Oral Pigmentation Index (DOPI) was used to determine the initial severity of pigmentation and track both reduction and potential repigmentation over time. The Gingival Melanosis Record (GMR) was used to evaluate the presence and extent of pigmentation and monitor recurrence after 1 and 12 months. Both the Er,Cr:YSGG laser and surgical scalpel similarly reduced GMR and DOPI scores over time, without significant differences at 12 months (P > .05). Significant examiner variability was noted in GMR scoring (β = -1.2 for Examiner 2; P < .001). Power analysis indicated a higher confidence for detecting treatment effects in DOPI (75%) compared to GMR (55%). The Er,Cr:YSGG laser required longer surgery times (P < .001), treatment type did not influence postoperative pain levels, and patient smile satisfaction significantly improved (P < .001). Under the present conditions, the Er,Cr:YSGG laser and surgical scalpel were equally effective in reducing gingival hyperpigmentation. Although lasers offer better bleeding control and require less anesthesia than the scalpel technique, clinicians should also consider surgery duration, cost, and expertise when selecting a treatment method. Future research should focus on long-term outcomes and economic evaluations, utilizing standardized clinical measures.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"451-465"},"PeriodicalIF":0.0,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141768410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this series of four cases, we applied a reconstructive technique utilizing autogenous bone grafting using MT donor sites. Patients underwent a postoperative maintenance program, clinical examinations, and completion of a questionnaire to assess changes in the neurosensory function of the nasopalatine nerve. Study outcomes included the extent of bone reconstruction, postoperative neurosensory function of the nasopalatine nerve, and overall patient satisfaction. Cases were followed for a mean of 23.5±0.5 months. The technique consistently resulted in predictable bone reconstruction, either with delayed or immediate implantation and provisionalization. IF enucleation and reconstruction of the damaged extraction sockets resulted in no abnormal postoperative pain or paresthesia, and yielded high patient satisfaction. The use of autogenous bone grafts from the MT provides an optimal and simple solution for the management of extraction sockets adjacent to large IFs.

Despite successful root canal treatment, if the majority of bone support has been lost from periodontitis, the tooth may have a poor prognosis. In severe endodonticperiodontal lesions, the periodontal tissue regenerates poorly because of the significant loss of the periodontal ligament and cementum, poor tooth stability, and bone defect morphology that is unfavorable for bone regeneration. To overcome these difficult situations, osteotomy of the replantation bed and tooth replantation with horizontal rotation and deep placement may be performed. In the presented case, in order to improve periodontal regeneration, fibroblast growth factor-2 (FGF2) was applied to the artificially made periodontal defect. In addition, orthodontic extrusion of the deeply replaced tooth was performed for potential coronal migration of the periodontal tissue. This case presents a unique multidisciplinary method of treating severe endodontic-periodontal lesions using intentional replantation combined with FGF2 application and orthodontic extrusion.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"481-493"},"PeriodicalIF":0.0,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141768337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bone-to-implant contact (BIC) is one of the critical determinants of primary stability following implantation. However, its correlation to the implant stability quotient (ISQ) is uncertain. This study aims to determine the relationship between ISQ measurements and BIC in immediately placed implants.Materials and methods: An atraumatic extraction followed by immediate implant placements were performed on 33 teeth in seven human cadaver heads. The implant ISQ values were measured in four directions: buccal, lingual, mesial, and distal. The cadaver heads were imaged using cone-beam computed tomography (CBCT) to determine the linear BICs in the corresponding directions.Results: Among the twenty-eight implants analyzed, no correlations were observed between directional BICs and the corresponding ISQ values. ISQ measurements did not significantly differ between maxillary and mandibular implants, nor among different anatomical locations. Additionally, when solid contact was present at the implant shoulder, the ISQ values remained stable despite the absence of apical BIC.Conclusion: ISQ values alone appear to be poor predictors of BIC in immediately placed implants. Therefore, ISQ measurements should be interpreted alongside other assessment methods to more accurately evaluate implant stability.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"1-32"},"PeriodicalIF":0.0,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144612742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
